JAMES A. MARSH, OF CLEVELAND, OHIO.

VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 358,284, dated February22, 1887.

Application filed September 13, 1884. Serial No. 143,025. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES A. ll/IARSH, of Cleveland, county of Ouyahoga,State of Ohio, haveinvented certain new and useful Improvements inVapor-Stoves; and I. do hereby declare the following to be a full,clear, and exact description, such as will enable others skilled in theart to which it pertains to make or use the same.

My invention relates to vapor-burners; and it consists of thearrangement and construction of parts, as hereinafter described andparticularly claimed.

It is illustrated in the accompanying drawings, in which Figure 1 is aside view in elevation, partly in section; Fig. 2, a vertical section ofa main burner; Fig. 8, a cross-section on line a .c' of Fig. 2, showingthe deflector in elevationand the burner-cap in dotted lines; Fig. 4t,an end view of the side burner, partly in section, showing theheating-plate and connecting-pipes; Fig. 5, a sectional view in a planepassing through the axis of one of the connecting-pipes H on the line atm, Fig. 4.

In the drawings, qt is the retort or vaporizing-chamber, to whichgasoline is supplied through the pipe P in connection with a form ofsupply-pipe and safety-tank, Q X M f Gr, the latter-mentioned featuresconstituting the subject of my pending application filed on or about May25, 1885, Serial No. 167,341.

O is a main burner or cone similar to one described in Patent No.270,253, and is provided with upper, middle, and lower jet-openings, b bI).

B is a valve which controls the flow of fluid or gas from the retort A,in which the gas is generated, and is located in the chamber B, which isconnected to the retort by a suitable duct.

Beneath the chamber B is a chamber, D, which is designed as acommingling'chamber, and is providedwith a short induction tube oropening, D, for admitting gas and the outer air thereto, and an orifice,I), from which ignited gas 0 is conducted to jet-orifices in the burnerO, as hereinafter described. Leading from the retort A and chamber B" isa duct ,or pipe, a, which connects with a bottom crosspipe, to, andserves to convey gas or fluid to the needle jets or orifices d d.Beneath the jet d is located a needle-valve, 0, provided with awheel-handle and serving to control the flow of gas or fluid fromorifice (1 into the opening 1) in the bottom of the comminglingchamberD.

Extending laterally from the side of the chamber 13 is a pipe, H, whichserves to convey gas or fluid from said chamber to a side burner, K.This side burner is also p-rovided with jetopenings b" b If, and aheater-plate, S, is secured to the frame-work S at a point at one sideof the burner and beneath the same, so as to deflect the flame from apipe, F, leading from the commingling-chamber of the main burner, ashereinafter described. A duct or pipe, h, leads from the end of pipe Hto the burner-jet h beneath the side burner, K, as shown.

F represents a pipe leading from the side of the undercommingling-chamber, D, laterally and extending to apoint near thesideburner, K, as shown. The open end f of the pipe F is in proximity tothe pipe h, which connects pipe H and burner K, and to the lowerjetorifice, b. One object of the pipe F is to heat the burner K for thepurpose of initial starting, and another object is to automaticallyrekindle or reignite the gas in either burner when the light at thatpoint has been accidentally or otherwise extinguished.

In operating the apparatus, if it is desired simply to create andmaintain a constant flame at the open end of pipe F for initialstarting, valve 0, which controls jet-orifice cl, should be open toallow afull flow of gas,which will pass through pipe F, (to be lightedby hand at the open end of the same,).projecting a flame, 6, against theplate S of the side burner, K, and under orifices, b". If it is desiredto have pipe Fmaintained as an automatic relighting-tube, needle-orificed should be reduced by a par tial closing of valve 0, so that a verysmall quantity of gas will be discharged from orifice (1 into the openend of pipe D, the said gas taking with it into pipe F such a proportionof air as will render the compound explosive within the pipe F, in whichcondition ignition of the gas unlighted at either end will antomaticallyand necessarily ensueif one burner is out and the other lighted. WVhenthis condition of the gas is arrived at, if the gas at the side burneris lighted and burning, as above explained, and the main burner isunlighted, the

flame or explosion will be carried back from the jets b in the sideburner through pipe F to chamber D, through orifice Z), against andaround deflector R, and to jet-orifices b b I) in the main burner. 11',by any cause under this condition of things, the side burner shouldbecome extinguished, the flame or explosion carried from chamber D andpipe I will automatically relight the side burner. If it is desired tomaintain a light alone in the main burner, valve C may be operated tocut off all supply of gas to the side burner, and gas is then alonesupplied to the main bu rner through orifice d controlled by valve E.

The main burner has a deflector, R, (more fully shown and explained inPatent No. 270,253,) but itis manifest that any burner can be used atend of pipe F, provided it is placed in close proximity, so thatissuingjets can be lighted.

Another form of apparatus for accomplish ing the relighting of theburner when extinguished is made the subject of another pendingapplication, No.l97,37l,filed AprilLlSSG.

\Vhat I claim, and desire to secure by Letters Patent, is

1. In a gasoline-stove, a retort, a commingling-ehamber, and a ductconnecting said retort and said chamber, in combination with a sideburner and a communicating pipe between the said chamber and the sideburner, whereby ignited gas may be carried from one to the other, as andfor the purpose set forth.

2. In a gasoline-stove provided with burners, the combination, with saidburners, of a commingling-pipe having an open end in close proximity toone burner and the other end connected with an outer air-inlet and agas-jet orifice controlled by a valve for throwing the gas into saidpipe, substantially as described.

3. In agasolinestove provided with burners, one of which has aoommingling-chamber, the combinatiomwith said burners, ofa communieatingpipe with one end entering the commingling-chamber and the other endopen to the outer air in close proximity to the other burner, whereby agas-flame may be started and maintained at said open end,substantiallyas described.

4. The combination of a main burner having a retort orgenerating-chamber, a second ary chamber connected to the retort by aduct, side burners and pipes leading from said secondary chamber to theside burners, a pipe leading from the secondary chamber to thejetorifice of the main burner, and a valve located in saidsecondary'chamber, whereby the gas or fluid may be cut off from all theburners by the turning of said valve, as set forth.

5. The combination of a burner provided with a retort orgenerating-chamber, a pipe leading from said retort to a side burnerconnected therewith, a commingling chamber having an opening beneath it,and a supplemental pipe leading from the comminglingchamber and openingto the said side burners, and in proximity thereto, substantially as andfor the purpose described.

6. The combination of a main burner having a commingling-chamberprovided with lateral orifices, a comminglingchamber located at the sideof said burner and provided with orifices or jets on its inner side, apipe leading from said latter commingling-chamber to a side burner andhaving an open end thereat, and a chamber and duct through which themain burner and the side commingling chamber are connected, whereby themain burner may be automatically ignited, as Set forth.

7. The combination of a retort, a commingling-chamber, a duet forconveying gas from the retort to said chamber, a pipeleading from saidchamber to and in proximity to a side burner, and a side burner wherebycommingled air and gas are conveyed from the commingling-chamber to theexposed surfaces of the side burners, as set forth.

In testimony whereof I affix my signature, in presence of two witnesses.

JAMES A. MARSH.
